Raspberry Pi - access from the internet using no-ip

Anyway...  As part of my iPlayer custom podcast solution I needed to be able to connect to my Pi externally over the internet.

Sign up for a host with

My ISP assigns IP addresses dynamically (pretty typical but not very useful for accessing from the internet), so I setup a free account with who offer a free dynamic dns service whereby they provide you with a URL (e.g. and they redirect internet traffic from that URL to your IP address.

You can either login to and update your ip address manually, as and when it changes (not practical!), or no-ip provide client software which will run in the background on your Pi and periodically update your no-ip host with your IP address.

Note - Its important you create yourself an account and add a host on no-ip before installing the client as you will need your account details as part of the install.

Install no-ip client
(most of this detail is taken from but there are a few discrepancies)

Create a directory for the client software

mkdir /home/pi/noip
cd /home/pi/noip

Download the client software


Extract the archive

tar vzxf noip-duc-linux.tar.gz

Navigate to the archive directory
Note - use 'ls' to check the directory name create when the archive was extracted, it was noip-2.1.9-1 when I installed the client.

cd noip-2.1.9-1

Compile and install
The client was compiled and installed on the Raspberry Pi, using the following commands:

sudo make
sudo make install

During the install I was asked to proide my login, password and a refresh interval.

Run the client
The client is run using the following command:

sudo /usr/local/bin/noip2

The client runs continuously until shutdown or the Raspberry Pi is shutdown, if you want to set up your Pi so the no-ip client is started at boot, check out this blog which describes how to configure the application to start at boot.

I then had to configure my broadband router to forward the specific port I wanted my Pi to service (e.g. port 80 for www) to the internal IP address of my Raspberry Pi, see for more information about port forwarding guides and info; you may find setting up port forwarding simpler if your raspberry Pi has a static IP address, see this post on how to set a static IP address.


  1. Hi Martin,
    I've done as you've said, and gotten all the way through it, however, how come it doesn't ask which host I want to update using the Pi, or is it because I only have the one host to update?

    I've had it running for a while last night, set the update interval to 60 however, it isn't updating, so have removed the file at /usr/local/bin and ran sudo make install again and reconfig'd it. Is there anything else I should do?

    1. I vaguely remember when I installed the client and only had 1 host in no-ip it didn't ask to confirm - so this sounds ok.

      I would check the simple things, is the client actually running, run "ps -LA" and you should see no-ip2 running, also make sure your Pi is connected to the internet and can connect to no-ip run "ping" and make sure you get a response.

  3. Thanks for this Martin, took a lot of The Fear out of the process, for an init.d noob like myself.

  4. There is also this PHP client:

    1. What are the benefits of running a php client over the no-ip supplied one?

    2. None really. They do the same job, but I wrote the PHP client because I could not install the no-ip supplied one. So it is a matter of what language you prefer. If you program in PHP it will be easy to modify the PHP client to your needs .)

  5. So, if I install no-ip, can I go to internet?

    1. What do you want to do? Host a webserver, a vpn, get access to your pi via ssh from work? You tell me!

  7. i want to host a webserver for my monitoring system.. what should i do now?

    1. I think that depends on your requirements for a webserver. If your looking for a LAMP (linux, apache, mysql, php) setup, have a look at this, if you looking for a lightweight webserver, do a search for lighttpd, which you can install with sudo apt-get install lighttpd

  9. Followed this to the letter, but it just doesnt want to connect to my no-ip no idea why either.
    Using pwnpi3.0

    1. I have no experience of pwnpi. These instructions are based on the raspbian distribution. Are you presented with any error message?

  10. I have tried this over and over again. But I can not get it to work. I even set up a fresh load of the Pi OS on a new memory card. No luck. I made an account with No-ip. I setup the software on the Pi. I can access the default Wordpress website on other PCs on my network. Setup the No-ip on the Pi. I can ping the web address and the URL from the pi and all computers on the network. The router has been setup for port forwarding. But when I enter the No-ip URL I set up, it times out. Not matter what computer I use, one of off my network. Help please!!!!

    1. Very active forum I see. Oh well.

    2. I was just reading your original comment (while on my family holiday!) considering how to respond...

      If your looking for a forum try the raspberry pi one.

  11. Hi,
    i am trying to get access to my raspberry too.
    I installed no-ip on it but i don t exactly know which type of no-ip i have to select for my Hostname ?
    - DNS Host (A)
    - DNS Host (Round Robin)
    - DNS Alias (CNAME)
    - Port 80 Redirect Web Redirect
